There are some threads in this forum talking about the language file issues. I had encountered the same problem. The error message looks like this:

Warning: main(/www/users/china.cn/components/com_jpsubmissionary//language/) [function.main]: failed to open stream: No such device in /www/users/china.cn/administrator/components/com_jpsubmissionary/admin.jpsubmissionary.php on line 80


Finally I find that it's the problem of SQL script.

#Line 77
$query = "SELECT H_language FROM #__JoomlaProdigy_jpsubmissionary_configuration WHERE id = 0";

In some version of MySql, table name: #__JoomlaProdigy_jpsubmissionary_configuration is converted to lowercase.

so the SQL script should be :
$query = "SELECT H_language FROM #__joomlaprodigy_jpsubmissionary_configuration WHERE id = 0";
Otherwise the component cannot get any data from database.

Replace all "JoomlaProdigy" to "joomlaprodigy", the problem goes away.
Hope it helps..
